Is hair loss permanent?

Some causes of hair loss are temporary and can be reversed, while others are permanent.

Permanent hair loss results from progressive damage to your hair follicles, which are the structures in your skin that house and grow your individual strands of hair.

Conditions that may cause permanent hair loss include:

scarring (cicatricial) alopecia, which develops when inflammation destroys hair follicles

trichotillomania, which involves an irresistible urge to pull out hair

traction alopecia, which can happen when hairstyles such as braids pull on your hair too tightly

Do hot showers cause hair loss?

No, hot showers do not cause hair loss. But extremely hot water can damage keratin, the protein that makes up hair strands. It may also strip away the natural oils that keep your scalp and hair healthy.

If your hair is already dry or damaged, washing it in hot water can make it more likely to break.

To avoid damage, use lukewarm water instead of hot, avoid brushing and stretching your hair while it’s wet, and use a deeply moisturizing conditioner regularly.

Does caffeine stop hair loss?

There’s some research to suggest that may help with hair growth and slow down hair loss.

An older 2007 study found that caffeine blocked the effects of dihydrotestosterone (DHT) in male hair follicles. DHT is a hormone that’s linked to hair loss in people of all genders.

The caffeine also boosted hair root width and prolonged the growth phase of hair. It had a growth-promoting effect when tested on female hair follicles as well.

Because it’s a vasodilator, caffeine may also help improve blood flow to your scalp, promoting hair growth.

You can make your own coffee rinse for hair or buy caffeine shampoo.

Do hair transplants help hair loss?

Hair transplants involve taking hair from one area of your scalp and transplanting it into an area with hair thinning or balding.

Transplants may be successful for some people depending on the cause of the hair loss. But you’ll need enough hair to donate to the transplant, and you’ll need to wait several months for it to grow.

You can expect 10–80% of transplanted hair to grow back in 3–4 months. Talk with a dermatologist or a hair restoration specialist to find out whether a hair transplant is right for you.

Does smoking cause hair loss?

It’s widely known that smoking causes serious health problems, but it can also contribute to hair loss.

Smoking damages the hair follicle and reduces healthy blood flow. A 2021 study found that 425 out of 500 smokers had some degree of hair loss, while only 200 of 500 nonsmokers did.

The authors suggested that nicotine and other chemicals could speed up hair loss, but more research is needed to confirm this.

Smoking also increases the production of free radicals. These molecules react with others to cause oxidative stress, which can harm cellular DNA. A 2018 review found that cells in the hair follicles of scalps with hair loss are extremely sensitive to oxidative stress.
